When a user types $=$$$C$$$6$ in a cell, what does that mean?

Select one:

A$.$ The value will stay constant, referred to as "absolute reference".

B$.$ The cell will always show as a dollar value since the user specifically referenced the dollar sign in its cell reference.

C$.$ The cell will reflect the text $"$C$6"$ since it has a dollar sign before each column and row listed.

D$.$ The user is making a relative cell reference and that if the formula is copied and pasted elsewhere that the cell will shift as appropriate.
